From the given choices the true statement is Surface winds blow parallel to isobars.
Answer: Option B
<u>Explanation:</u>
The winds which flow near the isobars, flow in the parallel direction of the isobars. They are not absolutely parallel to each other but are this much parallel that the purpose of the flight planning can be fulfilled with this.
These winds flow in perpendicular position to isobars which are present at that particular surface and they flow in this direction due to the acting of the force of friction in that area. This force of friction can also change the direction and the flow of the wind.
Answer:
Short Answer: Uplift and Erosion activities
Explanation:
Let's understand this briefly,
Name/Type - Grand Canyon (deep gorge)
Location - Northern Arizona (USA)
Formation - About 6 millions years ago
How - When the river (Colorado) started to cut channels through layers of sedimentary rocks
Formation Process - Weathering and Erosion
Forces which acted - Wind, Precipitation, Streams and snowmelt
Depth - 1830 m
According to question,
It is formed due to tectonic uplift in the region and due to vast erosion activities affected by enormous number of factors.
